SPEGIPIGATION forming part of Letters Patent No. 342,627, dated May 25,1886.

Application filed February 20, 1886. Serial No. 192,685. (No model.)

To an whom, it may concern.-

Be it known that I, JAMEs A. NEWMAN, a citizen of the UnitedStates,residing at Greenfield, in the county of Highland and State ofOhio, have invented new and useful Improvements in Cattle-Pumps, ofwhich the following is a specification.

My invention relates to cattlepumps-that is to say, pumps for raisingwater from wells wherein the pumping mechanism is set in motion andoperated by suitable automatic devices, the movement of thelatter beinginitiated by the approach of the cattle'to the trough and checked bytheir departure, whereby waste of water or the heating of a large bodyof previously-accumulated water'is avoided.

My invention consists in the mechanism, hereinafter set forth, forstarting and stopping the pumping mechanism, and in the several novelfeatures of construction and combinations of parts fully shown anddescribed herein, and definitely pointed out in the claims annexed tothis specification.

In the accompanying drawings, Figure 1 is a front elevation of thepumping mechanism, together with the starting and stopping devices. Fig.2 is a vertical section of Fig. 1, taken in the plane of the main shaft.Fig. 3 is a detail View showing the manner of connecting the cord-drumand the main gear.

In the said drawings, the reference-numeral 1 designates a pump of anysuitable form,having a pump-lever, 2, which reciprocates the ordinarypump rod whereby the water is raised. The water is delivered fromaspout, 3, to a trough, 4, which may be conveniently placed at any pointfor the accommodation of the cattle.

Connected with the pumplever is a pitman, 5, which is operated by acrank, 6, upon a crank-shaft, 7, which is driven through an ordinarytrain of gearing from a main shaft, 8, having a drum, 9, upon which iswound a cord, 10, sustaining a weight, 11, from which the motive poweris derived.

An escapement-wheel, 12, which engages with an escapement-lever, l3,regulates the revolution of the crank-shaft in the manner usual inmotors of this character.

i thin convenient distance from the trough is placed a pivoted platform,14, having an the teeth of the gear 17,which is intermediate between themain gear upon the shaft 8 and the crankshaft 7. This rod is normallythrown upward by a spring, 18, to bring its end into engagement withsaid gear and check its revolution. The end of the arm 15 is connectedwith the rod 16-a convenient construction being that shown, wherein theend of the arm is forked to straddle the rod and rest upon the spring18. This spring is of sufficient tension to raise the forward edge ofthe platform 14 and engage the stop-rod with the gear, thereby arrestingthe action of the pumping mechanism. The rear edge of the platform mayeither rest upon or be pivotally connected with or hinged to a suitablesupport.

Theoperation of the mechanism is as follows: The cord-drnm being woundup by a key, which fits upon the post 19,the apparatus is ready foraction. As the stock approach the trough they step upon the platform 14,and the weight depressing the arm 15 withdraws the stop-rod 16 from itsengagement with the gear 17, whereupon the pumping mechanism begins toact, the weight causing rotation of the crank-shaft, whereby the pitman5 is reciprocated. The water raised is delivered directly to thetrougl1,wl1e11ce it is consumed by the stock, and the instant the demandhas been supplied the removal of weight from the platform 14 permits thestop-rod to rise and arrest the action of the pumping machinery. Bythese means no more water is drawn than is used, and when drawn it isfresh and cool, and therefore more likely to promote the health of thecattle.

It is evident that I may employ a spring as. a motor instead of aweight, and the train of driving-gears may be modified in various wayswithout departing from my invention, and the construction andarrangement of parts may also be varied in several particulars.

' The pitman 5 may be attached to the suckerrod direct, or to the handle2 of the pump, as maybe desired, and the mechanism may be -used with anykind or construction of pump for raising water. The cord-drum 9 isconnected with the main gear-wheel upon the same shaftby means of aspring-actuated pawl mounted on the gear and engaging with a ratchetrigidly mounted on the shaft carrying both the gear and the drum. Thisconstruction is precisely similar to that adopted in clock'gearing ormotors deriving their motive power from a weight.

\Vhat I claim is 1, In a cattle-pump, the combination, with a train ofactuating mechanism connected with the pump, of a pivoted platformdepressed by the weight of the stock, a brake'rod or stop connected tosaid platform to rise and fall therewith, and having an end adapted toengage one of the gears of the mechanism, and a spring directlyconnected with the rod and raising both rod and platform to arrest theoperation, substantially as described.
